What's the story on the 15's

[Big Q]

Curious to know if the 15's have a full forged bottom end and what kind of HP they are capable of supporting. I have a full bolt on 14 GT which I love but I'm looking at either forging the bottom end and probably having to upgrade the MT82 to support more power or am considering returning it to stock and upgrading to a 15 or possibly 16 automatic at the end of the year.

I am curious to know why people are under the impression that the '15 motors are "fully forged".

It's an 11-14 motor, with Boss Rods, and better heads/cams.

This is what I have read as well.

I believe they also have forged steel crank and the Pistons use a different casting process and they are supposed to be stronger as well.

Like I posted, the '15 engine is basically an 11-14 engine, but with better flowing heads, larger cams, and Boss Rods.

The crank is pretty much the same. The pistons are pretty much the same.
